Getting the relaxable kernel to run on a fresh install with a higher kernel version. #14

Hi!

I found a slight issue trying to do a fresh install of Proxmox 6 on top of Debian 10 on my G6.

The stock kernel with a new Proxmox 6 install has a higher version number than the kernel included here, so after installing I had to edit my grub defaults.

I've found this which lets me find out the string I need to add to /etc/grub/default to boot the right kernel

If you edit /etc/default/grub to contain

DEFAULT=saved GRUB_SAVEDEFAULT=true

Then I ran update-grub and rebooted.

Then I selected 'Advanced Options' and then chose the relaxable-rmrr kernel from the list.

and all should be fine(TM) for each reboot from then on.

I think you could probably then remove the existing proxmox kernel, although last time I tried it wanted to remove all of proxmox-ve.

Okay so none of that works. See my last post for what I finally did to get it working.

Kind regards, Jessica

Hmm. No that didn't fix it, booted right back into the standard kernel :/

I'm lost!

Okay, more head scratching and I just force purged the original proxmox kernel, and grub automagically got rid of the old entry.

dpkg --purge --force-depends pve-kernel-5.4.143-1-pve

(In my case)

Then I needed to fix the package to it tells apt that pve-kernel-5.4 is satisfied so had to rebuild the debian package with

dpkg-deb -x pve-kernel-5.4.124-1-pve-relaxablermrr_5.4.124-1_amd64.deb tmpdir

Then dpkg-deb --control pve-kernel-5.4.124-1-pve-relaxablermrr_5.4.124-1_amd64.deb tmpdir

Then edit tmpdir/DEBIAN/control And change the following line from Provides: linux-image, linux-image-2.6 to Provides: linux-image, linux-image-2.6, pve-kernel-5.4 Then go to the directory that contains tmpdir and build the debian package dpkg -b tmpdir pve-kernel-5.4-relaxablermrr.deb

Then install the new package dpkg -i pve-kernel-5.4-relaxablermrr.deb

Which should replace the existing package, but also convince apt that everything is working fine...

Hopefully this helps someone else out :)

Kind regards, Jessica

alternatively, I was able to select the default kernel in grub via this method: https://unix.stackexchange.com/a/327686

basically (on my system) setting /etc/default/grub

GRUB_DEFAULT="gnulinux-advanced-07bb498a-8a1f-4c75-964a-e1473b8fc610>gnulinux-5.4.124-1-pve-relaxablermrr-advanced-07bb498a-8a1f-4c75-964a-e1473b8fc610"
